Each Fan Innerstave set contains 20 square feet of wood, replicating 100% of the surface area of 225L barrel and providing similar extraction as a new premium oak barrel. The set is designed for easy attachment in wine tanks containing fan system hardware and can be applied in all phases of winemaking.

Also providing wineries the opportunity to obtain premium oak barrel character in larger wine vessels, Fan Innerstave is an alternative cost saving source over traditional premium oak barrels.
